Cowen-Douglas类中无重数的齐次算子

Multiplicity-free homogeneous operators in the Cowen-Douglas class

Adam Korányi, Gadadhar Misra

摘要:

在最近的一篇论文中,作者构造了单位圆盘$\mathbb D$的Cowen-Douglas类中的一大类算子,它们关于由单位圆盘$\mathbb{D}$的双全纯自同构构成的Möb群的作用是{ \em齐性}的.这些运算符中的每一个的{ \em关联表示}是{ \em多重性自由}。本文给出了Cowen-Douglas类中所有具有多重性自由伴随表示的齐次算子的一个不同的独立构造,并证明了它们与以前构造的例子完全相同.

英文摘要:

In a recent paper, the authors have constructed a large class of operators in the Cowen-Douglas class Cowen-Douglas class of the unit disc $\mathbb D$ which are {\em homogeneous} with respect to the action of the group Möb -- the Möbius group consisting of bi-holomorphic automorphisms of the unit disc $\mathbb{D}$. The {\em associated representation} for each of these operators is {\em multiplicity free}. Here we give a different independent construction of all homogeneous operators in the Cowen-Douglas class with multiplicity free associated representation and verify that they are exactly the examples constructed previously.
